Hi,sigurd Yes,I have gone through that git repo you have mentioned in your comment and I have successfully interface mpu with nrf51822. I want to detect a tap(means I set my mpu on a board) if I tap the board my tap must get detected ( print the message on the screen single tap detected).I want to do this without using of DMP feature of mpu.i want to do that using just raw values of mpu.ho do I do this? When my bord is on horizontal position with +-2g setting and using low power mode I got this mpu readings X=32767,Y=32767,Z=48767 how can I detect a tap with the help of this reading?
